Abstract
A loading tube for installation in the body of a perforating gun is disclosed. The loading tube holds a plurality of shaped charges whose detonation is electrically initiated, and the loading tube, when installed in the body, comprises at least a portion of the electrical circuit used to initiate detonation the shaped charge. In one embodiment, the loading tube comprises the hot portion of the electrical circuit, the body comprises the ground portion of the electrical circuit and the loading tube and the body are insulated from one another. Alternatively, the loading tube may comprise two distinct portions of conductive material which are electrically isolated from one another where the two portions of conductive material comprise the hot and ground portions of the electrical circuit. Additionally, a loading tube according to the present invention may comprise a conductor which is disposed in the loading tube near the outer surface of the loading tube and which is insulated from the loading tube. A system is disclosed comprising a loading tube having the aforesaid characteristics and a method is provided which utilizes the loading tube as a portion of the electrical circuit to initiate detonation of the charges.
